FWIW... I've been fiddling around with Yellow Jackets in my LSC, paired with both 6L6s and 6V6s. Both combos sound great. I'm amazed at how apparent the EL84 character shines through, especially in the Clean channel cranked just a bit (like 2:00).
Put those YJs in the outer sockets and flip it to 50w mode, and all you have cooking are the EL84s, running at something like 25-30 watts. At that point it seems to depend on how I play, and it's easy to make it sound pretty damned AC30ish. The amp is very very responsive in this configuration, and seems to breathe through its teeth, if you will, in the same way the Vox always sounded to me.
The point is that if you aren't going to get a vintage Vox, you can probably get close with any of the amps listed above that use EL84s. I'm partial to the LSC because of the versatile configuration and power options, plus simple layout... LSS is good too, but perhaps less flexible. In any case, your emulation will depend on your playing style as much as, or more than, the amp's guts.
